JIG FOR FORMING HANDLE HOLES IN DOORS OR THE LIKE Specification of Letters Patent. Pate ited Apr. 11, 1922.

Application filed June 26, 1920, Serial No. 391,886. Renewed February 23, 1922. Serial No. 538,697.

T 0 all whom it may concern.

Be it known that I, LEON OTTINGER, a citizen of the United States, and a resident of the city of New York, county and State of New York, have invented certain new and useful lrli jprovements in Jigs for Forming Handle oles in Doors or the like, of which the following is a description.

The present invention relates to improvements in methods and means for forming handle holes in doors or the like, and particularly such holes in cooperative relation with the latches or looks of automobile doors. Heretofore other methods or apparatus employed for such purpose have been unreliable, time-consuming, and did not produce an accurately aligned hole, so that a perfect fitting of the handles could not be accomplished, and consequently'the latch, in most cases, was defective in operation. Furthermore, the exposed handle in most cases was unsightly in appearance because of its untrue position. These methods, it should be pointed out, consume very considerable time and expenditure of labor, especially in-the matter of custom built or high priced bodies, and the unsatisfactory results obtained would seem to be entirely incommensurate.

It is proposed in the present invention, therefore, to prepare the door for receiving the handle in a manner as to positively produce a pro-per fitting and alignment of the handle with the latch when installed, and with a great saving of time and labor over the previous methods. To this end it is proposed to provide as a part of my invention, a jig adapted to be secured to the latch upon the door prior to the drilling of the hole for the handle shaft, and in connection therewith a series of tools for the purpose of producing the hole in proper and exact alignment with the openin of the roll back lever of the latch, and 1nto which the operating handle is adapted to be secured.

A further object of the invention is to provide in certain embodiments of the invention, a jig which may be employed for either right or left hand latches.

With these and other objects in view, embodiments of my invention are shown in the accompanying drawings, and these 6H1' bodiments will be hereinafter more fully de-' scribed with reference thereto, and the invention will be finally pointed out in the claims.

In the accompanying drawings:

Figure 1 is a View in elevation showing a latch at the inner side of an automobile door, and showing my improved jig in place thereon.

Figure 2 is a horizontal sectional View taken on the line 2-2 of Figure 1, and showing the first operation in the formation of the hole through the door, i. e., the producing of the pilot hole.

Figure 3 is a detail view of a guide member employed in connection with the jig.

Figures 4, 5, and 6 are horizontal sectional views showing the three steps subsequent to that shown in Figure 2 in the formation of the hole.

Figure 7 is a horizontal sectional view of the door with the hole completely formed therein, and provided with a thimble or bushing.

Figure 8 is a horizontal sectional view, with parts broken away, of a modified form of jig, and showing that portion of the same adapted to be engaged in the'roll back of a latch.

Figure 9 is a plan view of a further modified form of jig.

Figure 10 is a side view thereof.

Figure 11 is a horizontal sectional view through the door, showing a still further modified form of jig attached thereto.

Similar reference characters designate corresponding parts throughout the several figures of the drawings.

Referring to the drawings, and particularly Figures 1 and 2 thereof, the latch casing 20 is set in a recess 21 at the inner side of the door, and is provided with a roll back 22 rotatably mounted between the two faces of the casing in circular openings 23 and 24, and adapted to be oscillated to retract the bolt 25 by .means of a handle inserted through the roll back, as will be hereinafter more fully pointedout. In the present disclosure 1 have illustrated a bolt. of the expanding type, as disclosed in my U. S. Patent No. 1,312,199. A square passage 26 is provided within the roll back to receive the handle shaft, which is adapted to be inserted through an opening 27 (Fig. 7) in the frame of the 'door,and extending from the inner sideof the rollback, to the outer side of the door, the opening being threaded, as

at 28, and having a thimble or bushing 29 screwed therein for receiving the handle, which is adapted to have its bearing in the thimble or bushing, its shaft being inserted through the opening 27 into the opening of the opening is accomplished by means of a jig plate 30, having a plurality (three preferably) of feet 31, having threaded portions 32 engaged in threaded holes 33 formed in the plate, a shoulder 34abutting the plate, and a transverse rod 35 to facilitate removal and attachment of the feet, the feet being adapted to be engaged at either side of the plate to permit of reversal of the plate, as will be presently more fully pointed out. The feet are adapted to rest upon the face of the latch so as to space the plate in true parallel relation thereto. This is desirable, as the latch casing is not always exactly flush and in a plane with the inner surface of the door, and it is essential in such cases where the plate extends beyond the latch casing, that the same be raised from the surface of the door.

Additional screw holes 33 are provided in the plate in suitable position so as to enable the position of the feet to be changed in the event that any obstructions or holes in the latch casing may prevent the proper engagement of the feet with the face plate.

The plate is secured in place by screws 36 engaged in the frame of the door through holes 37 in the jig plate, a suitable number of these screws being provided to enable the screws to be engaged with parts of the frame which are not obstructed by the handle of the latch, screws, or other metal attachments. It will be understood that if desired, tapped holes may be provided in the latch casing to receive attachment screws.

A hole 38 is provided in the jig plate to accommodate the knob 39 provided in the latch, it being understood that the plate may be provided with any necessary openings for other projections on the latch, depending on the particular construction thereof, and that in such cases when there are no projections,

the plate .may be solid.

A hole 40 is provided in the jig plate above the passage through the roll back, in which is secured a positioning member comprising a threaded shank portion 41 engaged in the opening, a flange 42 engaging the inner side of the plate, and a nut 39 screwed upon the threaded shank into engagement with the upper surface of the plate securely fixing the parts in place. A downwardly extending portion 43, square in cross section,

is provided on the end of the shank portion, and is engaged within the opening through the roll back, the same being slightly smaller in cross sectional area than the hole in the roll back. A circular passage 44 extends axially through the positioning member. By first loosely engaging the end 43 in the passage through the roll back, and thereupon turning the late, the end 43 of the drill guide is tight y engaged with the side walls of the passage, and, therefore, an'exact centralization of the passage 44 relatively to the passage of the roll. back, results,even in those cases where the roll back passage is not accurately formed, and which is not an uncommon occurrence. Thus, it often happens, in casting the roll back, that in the extraction of the core, the area of the end, of the rectangular passage from which the core is withdrawn is appreciably greater than the area of the'other portions of this passage. The positioning member is reversible in the opening 40 to enable the plate to be secured to either right or left hand latches, the feet, as above pointed out, also being reversible for this purpose.

lVhen the jig is secured in place, the next step in the formation of the hole through the door frame is the drilling of a pilot hole 45, and for this purpose there is provided a drill 46, which is engaged in the passage 44, and, as clearly indicated in Figure 2, is drilled through the Wooden frame of the door, and also through the thin sheet metal outer covering or sheath 47 of the door. The drill is thereupon withdrawn, and a counterboring tool, as shown in Figure 4, is used for the purpose of removing a circular piece of metal from the outer covering or sheath concentric to the drilled pilot hole, and of slightly greater diameter than the final passage to be formed through the frame. This comprises a cup-shaped portion 48, having annular crown teeth 49, a

shank 50 and a pilot rod extension 51 projecting from the portion 48, and adapted to be engaged in the pilot hole through the door frame to thereby align the tool so that the hole formed thereby will be in true concentric and aligned relation to the hole in the roll back.

A boring tool, as illustrated in Figure 5, is then employed, and comprises a boring portion 52 of suitable diameter to bore a hole of greater size than the opening throu h the roll back, a shank portion 53 and a pi 0t rod or extension portion 54, adapted to enter the drilled pilot hole through the door frame to align the tool, and also as the hole is bored, to enter the passage 44 through the drill guide portion of the jig. A stop collar 55 is provided on the shank, and is provided with a set screw 56 adapted to fix its position, so as to limit the insertion of the drill and thereby prevent its engaging the metal thus formed is in exact concentric and aligned relation withthe opening through the roll back, and has its axis in true rightangular relation with the plane of rotation of the roll back.

Finally the hole is screw threaded at its outer end by means of a threading tool 57, having a guide extension portion 58 adapted to be first inserted in the hole to support the tool in a manner as to cause the thread forming teeth to be properly engaged. The thimble or bushing 29 is then inserted in the threaded portion 28 of the hole 27, as before pointed out, .and the door is now ready to. have the handle mounted therein and attached to the latch.

In Figure 8 I have illustrated a modified form of reversible drill guide member for the jig plate, comprising ani nter-ior'ly threaded bushing 16 disposed in"a:n'opening 61 of the plate, and having a laterally extending flange 62 engaging the face of the plate, and secured thereto by a screw 63. Within the bushing there is adjustably mounted a tubular member 64 exteriorly threaded to engage the threads of the bushing, being provided at its, lower end with a conical portion-65 adapted to enter and snugly engage the opening through the roll back, and at its.other end with a squared wrench engagement portion 66. A fixing nut 67 for maintaining the position of adjustment of the member 64 is screwed upon the threaded portion against the end of the bushing. The bushing, it will be noted, projects above and below the plate an equal distance, so that it will bear the same relation to the latch in either the illustrated position of the member, or the reverse position. The end of the tubular member engaging the hole in the roll back may, if desired, be square, as in the first described form of the invention.

In the present embodiment. I have illustrated a modified form of supporting foot, comprising a post 68 soldered or otherwise suitably secured in an opening in the plate,

and projecting equally above and below the plate.

I have illustrated in Figures 9 and 10 a 7 further modified form of reversible plate 70, provided with enlarged openings 71 and 72, similar in shape, and symmetrically p0 sitioned, a plurality of screw holes 73 at each end of the plate, fixed supporting feet 76 adapted to engage either the opening 77 in the plate, or the opening 78, said feet being flanged, as at 79, and provided with a screw-threaded shank upon which there is engaged a wide nut 80 to attach the feet to the plate. At the upper portion of the plate and medially of the openings 71 and 72, there is provided a drill guide membercomprising a tubular post 81 engaged in an opening 82 of the plate, and provided with a flange 83 secured to the plate by screws 84, the post being provided at its lower end with a square portion 85, adapted to be engaged within the opening of the roll back. This plate, it will be noted, may be used for drilling holes in either right or left hand doors, the feet 76 being positioned, as illustrated in the one case, and engaged in the openings 78 in the other case, the openings 71 and 72 respectively, engaging the projecting knob 36 of the latch. The plurality of screw holes 73 will enable the attachment screws to be conveniently positioned to secure the plate to the latch.

In Figure 11 I have illustrated a still further modified form of plate particularly adapted for use with a latch of the type disclosed in my U. S. patent above referred to, and in which the bolt 25 is provided with an expansion member 86 adapted, as the bolt is projected, to be expanded transversely relatively to the bolt. This feature of the latch is utilized for securing the jig in place upon the latch, the jig plate 87 being provided at its forward end with a downwardly and inwardly bent portion 88, the upwardly "tion, thereby tightly drawing the jig plate towards the latch. The jig plate is secured at its other end to the door frame by means of a screw or screws 89.
